FIGS. 1 to 5 illustrate a display device according to an embodiment ofthe invention.

As shown in FIGS. 1 to 5, a display device 1 according to an embodimentof the invention may include a plurality of panel assemblies 10 and 20,in which at least a portion is curved.

As shown in FIGS. 1 and 2, the display device 1 may include a frame (ora center frame) 30 and the panel assemblies 10 and 20 attached to theframe 30.

The frame 30 may be a component structurally supporting the displaydevice 1. The frame 30 may be made of aluminum, so as to providerigidity.

The frame 30 may be formed in a curved shape. For example, the frame 30may be formed in at least one of a concave curved shape and/or a convexcurved shape. For example, the frame 30 may be configured such that theframe 30 of the concave curved shape and the frame 30 of the convexcurved shape are disposed.

The panel assemblies 10 and 20 may be formed in a curved shape. In otherwords, the panel assemblies 10 and 20 may be formed in a curved shapecorresponding to the frame 30. In other words, the panel assemblies 10and 20 may be formed in at least one of a concave curved shape and/or aconvex curved shape.

The panel assemblies 10 and 20 may include a front panel 10 and a rearpanel 20. The front panel 10 and the rear panel 20 may be positioned onone surface and the other surface of the frame 30. For example, thefront panel 10 including first to fourth front panels 11, 13, 15, and 17may be positioned on one surface of the frame 30, and the rear panel 20including first to fourth rear panels 21, 23, 25, and 27 may bepositioned on the other surface of the frame 30.

The panel assemblies 10 and 20 may be disposed such that their longsides are perpendicular to the ground. Namely, the panel assemblies 10and 20 may be disposed such that their long sides are adjacent to eachother in a longitudinal direction.

Alternatively, the panel assemblies 10 and 20 may be disposed such thattheir short sides are perpendicular to the ground. In this instance, itmay be appropriate to display a long side of an image in a horizontaldirection.

The panel assemblies 10 and 20 on one surface and the other surface ofthe frame 30 may have shapes corresponding to each other. For example,the first front panel 11 and the fourth rear panel 27 may have a concaveshape and a convex shape corresponding to each other.

Because the panel assemblies 10 and 20 are disposed on one surface andthe other surface of the frame 30 as described above, a displayed imagemay be observed at various positions. For example, when a panel isinstalled in a lobby such as an airport, an image can be effectivelytransferred.

As shown in FIGS. 3 and 4, the display device 1 may be configured invarious forms.

As shown in FIG. 3A, the display device 1 may have a shape based onfirst to fourth frames 31 to 34. For example, the third and fourthframes 33 and 34 of a concave shape may be positioned subsequent to thefirst and second frames 31 and 32 of a convex shape. In this instance,the display device 1 may have a wave shape.

As shown in FIG. 3B, the display device 1 may have a shape based onfirst to third frames 31 to 33. For example, a plurality ofconvex-shaped frames 30 and a concave-shaped frame 30 may be coupled, orvice versa.

As shown in FIG. 3C, the display device 1 may be configured such thatthe number of concave-shaped frame 30 is different from the number ofconvex-shaped frame 30. Namely, the left and right sides of the displaydevice 1 may be asymmetrical.

As shown in FIGS. 4A and 4B, at least a portion of the display device 1may be disposed in a circular shape. Namely, a plurality ofconcave-shaped frames 30 may be successively disposed.

As shown in FIG. 4A, when first to fourth frames 31 to 34 of a concaveshape are successively disposed, a portion of the display device 1 maybe formed in a circular shape.

As shown in FIG. 4B, when frames 30 of the same shape are successivelydisposed, the display device 1 may be entirely formed in a circularshape.

As shown in 5A and 5B, at least a portion of the display device 1according to the embodiment of the invention may be flat formed.

As shown in FIG. 5A, the display device 1 may be entirely formed in aflat shape. For example, panel assemblies 10 and 20 may be disposed onboth side surfaces of a flat frame 30. The adjacent panel assemblies 10and 20 may partially overlap each other. The panel assemblies 10 and 20may be coupled in predetermined order in consideration of theoverlapping.

As shown in FIG. 5B, a portion of each of panel assemblies 10 and 20 maybe in a flat shape, and another portion may be in a curved shape. Forexample, first and fourth front panels 11 and 17, first and fourth rearpanels 21 and 27, and frames 30 corresponding to the first and fourthfront and rear panels may have a flat shape. On the other hand, secondand third front panels 13 and 15, second and third rear panels 23 and25, and frames 30 corresponding to the second and third front and rearpanels may have a curved shape.

FIGS. 6 to 15 illustrate configuration of a stand assembly of thedisplay device according to the embodiment of the invention.

As shown in FIGS. 6 to 15, the display device 1 according to theembodiment of the invention may include a stand assembly 40 supportingthe display device 1.

As shown in FIGS. 6 and 7, the stand assembly 40 may include a pluralityof stand assemblies. For example, the stand assembly 40 may includefirst to fourth stand assemblies 40 a to 40 d.

The first to fourth stand assemblies 40 a to 40 d may be independentlyassembled. The independently assembled first to fourth stand assemblies40 a to 40 d may be coupled to form one stand assembly 40. The first tofourth stand assemblies 40 a to 40 d may correspond to a specificlocation of the curved display device 1. In the following description, adescription of one of the stand assembly 40 and the first to fourthstand assemblies 40 a to 40 d will be replaced with a description of theothers because the stand assemblies 40 and 40 a to 40 d may have adifference only in a curved shape.

The stand assembly 40 may include a base 41, a stand frame 45 that iscoupled to the base 41 and stands, a frame bar 43 coupled to the standframe 45 in a transverse direction, and a base frame 47 on the base 41.

The base 41 may be formed in a plate shape. Namely, the base 41 may forma bottom surface of the stand assembly 40. The base 41 may include aplurality of through holes for coupling various components.

The stand frame 45 may be a bar coupled to the base 41 in a longitudinaldirection. One end of the stand frame 45 may be coupled to the base 41,and the other end may upwardly face. The stand frame 45 may includefirst and second stand frames 45 a and 45 b (see FIG. 8).

The frame bar 43 may be coupled to the stand frame 45. In other words,the frame bar 43 may be transversely coupled to the stand frame 45longitudinally coupled to the base 41. The frame bar 43 may bepositioned between the first and second stand frames 45 a and 45 b. Theframe bar 43 may strengthen rigidity of the stand frame 45. The framebar 43 may have a curved shape corresponding to a disposition of thestand frame 45.

The base frame 47 may be coupled to a plane of the base 41. The baseframe 47 coupled to the plane of the base 41 may provide rigidity forthe base 41 so that the base 41 is not twisted. The base frame 47 mayinclude first and second base frames 47 a and 47 b coupled to the base41 along both sides of the base 41.

As shown in FIG. 8, the stand assembly 40 may include first and secondframe bars 43 a and 43 b positioned between the first and second standframes 45 a and 45 b. The first and second frame bars 43 a and 43 b mayprovide rigidity for a structure of the first and second stand frames 45a and 45 b. The first and second frame bars 43 a and 43 b may make thefirst and second stand frames 45 a and 45 b be spaced apart from eachother. The frame 30 may be inserted in a separation space formed by thefirst and second frame bars 43 a and 43 b.

The stand assembly 40 may include a ball caster 49.

The ball casters 49 may be coupled to a plurality of positions of alower surface of the base 41, so as to support the stand assembly 40.The ball casters 49 may enable each stand assembly 40 to move. Forexample, a ball and/or a wheel included in the ball caster 49 may rotateand thus may change a position of the stand assembly 40.

The ball caster 49 may be coupled to the base 41. For example, the ballcaster 49 may be coupled to the second base 41 b underlying the firstbase 41 a.

As shown in FIG. 9, the frame 30 may be coupled to the stand assembly40. The frame 30 may be positioned between the first and second standframes 45 a and 45 b. For example, the frame 30 may be positionedbetween 1 a, 1 b and 1 c stand frames 45 a 1, 45 a 2 and 45 a 3 and 2 a,2 b and 2 c stand frames 45 b 1, 45 b 2 and 45 b 3.

The frame bar 43 may be positioned between the 1 a, 1 b and 1 c standframes 45 a 1, 45 a 2 and 45 a 3 and the 2 a, 2 b and 2 c stand frames45 b 1, 45 b 2 and 45 b 3. For example, the second frame bar 43 b may becoupled to the 1 a, 1 b and 1 c stand frames 45 a 1, 45 a 2 and 45 a 3and the 2 a, 2 b and 2 c stand frames 45 b 1, 45 b 2 and 45 b 3.

The second frame bar 43 b may provide rigidity for the 1 a, 1 b and 1 cstand frames 45 a 1, 45 a 2 and 45 a 3 and the 2 a, 2 b and 2 c standframes 45 b 1, 45 b 2 and 45 b 3 and form a frame coupling space (wherethe frame 30 will be disposed and coupled) between the 1 a, 1 b and 1 cstand frames 45 a 1, 45 a 2 and 45 a 3 and the 2 a, 2 b and 2 c standframes 45 b 1, 45 b 2 and 45 b 3. For example, when the second frame bar43 b has a first thickness T1, and a distance between the 1 a, 1 b and 1c stand frames 45 a 1, 45 a 2 and 45 a 3 and the 2 a, 2 b and 2 c standframes 45 b 1, 45 b 2 and 45 b 3 is a second thickness T2, the firstthickness T1 may be the same as the second thickness T2. The first andsecond thicknesses T1 and T2 may be equal to or greater than a thickness(i.e., a third thickness) T3 of the frame 30. Thus, the frame 30 may befixed in a form to be placed on the second frame bar 43 b.

As shown in FIGS. 10 to 12, the stand assembly 40 of the display device1 according to the embodiment of the invention may be fixed in asuitable form using the ball casters 49 and a fixer 42.

As shown in FIG. 10, the ball casters 49 may be coupled to bottomsurfaces of the first to fourth stand assemblies 40 a to 40 d of thedisplay device 1 according to the embodiment of the invention. The firstto fourth stand assemblies 40 a to 40 d may adjust their position usingthe ball casters 49.

As shown in FIG. 11, an operator may dispose the first and second standassemblies 40 a and 40 b adjacent to each other and then dispose thefixer 42.

The first and second stand assemblies 40 a and 40 b may include first tofourth stand coupling holes Ha1, Ha2, Hb1, and Hb2. The fixer 42 mayinclude first to fourth fixer coupling holes Hc1, Hc2, Hd1, and Hd2. Afirst diameter D1 of each of the first to fourth stand coupling holesHa1, Ha2, Hb1, and Hb2 may be less than a second diameter D2 of each ofthe first to fourth fixer coupling holes Hc1, Hc2, Hd1, and Hd2.

As shown in FIG. 12A, the first and second stand assemblies 40 a and 40b may not be initially positioned in place. This may be perceivedintuitively by the first to fourth stand coupling holes Ha1, Ha2, Hb1,and Hb2 observed through the first to fourth fixer coupling holes Hc1,Hc2, Hd1, and Hd2. For example, because the second stand assembly 40 bis not positioned in place, the fourth stand coupling hole Hb2 observedthrough the fourth fixer coupling hole Hd2 may be out of position, andthe third stand coupling hole Hb1 may not be observed through the thirdfixer coupling hole Hd1.

As shown in FIG. 12B, the operator may adjust the position of the firstand second stand assemblies 40 a and 40 b. The position adjustment maybe easily performed using ball casters 49 a and 49 b on the bottomsurfaces of the first and second stand assemblies 40 a and 40 b.

The fact that the first and second stand assemblies 40 a and 40 b arepositioned in place may be easily determined based on whether or not thefirst to fourth stand coupling holes Ha1, Ha2, Hb1, and Hb2 arerespectively positioned in the center of the first to fourth fixercoupling holes Hc1, Hc2, Hd1, and Hd2. Namely, the operator may easilydispose the first and second stand assemblies 40 a and 40 b in placeusing the ball casters 49 a and 49 b and the fixer 42 without using aseparate tool, etc.

As shown in FIG. 13, a stand cover supporter 41 c may be coupled to thebase 141.

The stand cover supporter 41 c may fix the two adjacent stand assemblies40. For example, the stand cover supporter 41 c may be coupled to thebase 141 so that the first and second stand assemblies 40 a and 40 b areconnected to each other. For example, a screw 41 d may pass through thestand cover supporter 41 c and a coupling hole 41 e and may couple thestand cover supporter 41 c to the base 141.

The plurality of stand cover supporters 41 c may be used to connect thetwo adjacent stand assemblies 40. For example, the two stand coversupporters 41 c may be positioned between the first and second standassemblies 40 a and 40 b and coupled to them.

As shown in FIGS. 14 and 15, the components of the display device 1 maybe coupled to the stand assembly 40. The component of the display device1 may include an electronic unit supplying electrical signals and/orelectric power. The panel assemblies 10 and 20 (see FIG. 26) displayingan image of the display device 1 may be configured to be relativelythin. The panel assemblies 10 and 20 (see FIG. 26) may be formed in athin and beautiful shape by applying an organic light emitting diode(OLED) display panel by way of example. Thus, the components necessaryfor an operation of the panel assemblies 10 and 20 (see FIG. 26) may bedisposed at the stand assembly 40.

The component of the display device 1 may be coupled to the standassembly 40 at different positions. For example, a portion of thecomponent may be coupled to the stand frame 45, and another portion ofthe component may be disposed on the base frame 47 in accordance withcharacteristics of the component.

The components of the display device 1 may be disposed in both sideareas of the stand frame 45. The display device 1 may include the firstand second panel assemblies 10 and 20. Namely, the display device 1 mayinclude the first panel assembly 10 facing one side and the second panelassembly 20 facing the other side. Thus, a component corresponding tothe first panel assembly 10 may be disposed in one side area, and acomponent corresponding to the second panel assembly 20 may be disposedin the other side area. Namely, components 51 a, 53 a, and 55 acorresponding to the first panel assembly 10 may be disposed in one sidearea, and components 51 b, 53 b, and 55 b corresponding to the secondpanel assembly 20 may be disposed in the other side area.

The components of the display device 1 may include power units 51 a and51 b, T-con units 53 a and 53 b, and printed circuit board (PCB) units55 a and 55 b. The components may be attached to the stand frame 45 orattached to the base frame 47. Such an arrangement of the components maybe to minimize a width, a length, and/or a volume of the stand assembly40. For example, the T-con units 53 a and 53 b and/or the PCB units 55 aand 55 b having a relatively large area may be attached to the standframe 45. When the component having a relatively large area islongitudinally disposed on the stand frame 45, a width of the Z-X planeof the base frame 47 can be prevented from being increased. Such anarrangement of the components may be to minimize a noise that may occurbetween the panel assemblies 10 and 20 and the components exchangingsignals with the panel assemblies 10 and 20. For example, the T-conunits 53 a and 53 b and/or the PCB units 55 a and 55 b may transmit animage signal to the panel assemblies 10 and 20. When a transmission pathof the image signal becomes longer, a likelihood of occurrence of thenoise may increase. Thus, the T-con units 53 a and 53 b and/or the PCBunits 55 a and 55 b may be disposed on the stand frame 45 near to thepanel assemblies 10 and 20. Such an arrangement may be to minimizeinterference between operations of the components. For example, thepower units 51 a and 51 b generating heat may be attached to the baseframe 47. By disposing the power units 51 a and 51 b at a distance fromother components, the power units 51 a and 51 b can smoothly dissipateheat. Further, an influence of the heat dissipation on other componentscan be reduced.

FIGS. 16 to 25 illustrate configuration of a center frame assemblyaccording to the embodiment of the invention.

As shown in FIGS. 16 to 25, the display device 1 according to theembodiment of the invention may include a center frame assembly 30. Thecenter frame assembly 30 may be a component, to which the panelassemblies 10 and 20 (see FIG. 26) of the display device 1 are coupled.The center frame assembly 30 may guide the panel assemblies 10 and 20 tomaintain a curved shape.

As shown in FIG. 16, the center frame assembly 30 may include first tofourth center frames 31 to 34. The first to fourth center frames 31 to34 may be formed in a curved shape. For example, the first and secondcenter frames 31 and 32 may be formed in a concave curved shape, and thethird and fourth center frames 33 and 34 may be formed in a convexcurved shape.

The first to fourth center frames 31 to 34 may be coupled to the firstto fourth stand assemblies 40 a to 40 d. For example, the first tofourth center frames 31 to 34 may be coupled to upper sides of the standframes 45 of the first to fourth stand assemblies 40 a to 40 d.

A center frame bracket 70 may be coupled to a long side of the centerframe assembly 30. For example, a first center frame bracket 71 may bepositioned between the first and second center frames 31 and 32; asecond center frame bracket 73 may be positioned between the second andthird center frames 32 and 33; and a third center frame bracket 75 maybe positioned between the third and fourth center frames 33 and 34. Eachcenter frame bracket 70 may fix the adjacent center frames 30.

As shown in FIG. 17, after the center frame 30 is temporarily fixed tothe stand frame 45, the center frame 30 may be firmly fixed to the standframe 45 using a coupling means such as a bolt 66.

As shown in FIG. 18, first, second, and third through holes 46 a, 46 b,and 30 a communicating with one another may be formed in the 1 a and 2 astand frames 45 a 1 and 45 b 1 and the center frame 30. The bolt 66 maypass through the first, second, and third through holes 46 a, 46 b, and30 a and may be coupled to a nut 67.

As shown in FIGS. 19A, 19B and 20, the center frame 30 may have a shapecorresponding to the shape of the panel assemblies 10 and 20 that willbe coupled to the center frame 30.

As shown in FIGS. 19A and 19B, a first groove 36 a and a second groove36 b may be respectively formed on a first surface 35 a and a secondsurface 35 b of the center frame 30. The first and second grooves 36 aand 36 b may be formed by more depressing a portion of each of the firstand second surfaces 35 a and 35 b than another portion.

The first and second grooves 36 a and 36 b may correspond to a backstructure of the panel assemblies 10 and 20. For example, the first andsecond grooves 36 a and 36 b may be an area of the panel assemblies 10and 20 corresponding to a cable connected to the T-con units 53 a and 53b, the PCB units 55 a and 55 b, and/or the power units 51 a and 51 b.

As shown in FIG. 20, the first groove 36 a may be formed on the firstsurface 35 a, and the second groove 36 b may be formed on the secondsurface 35 b. The first groove 36 a may be positioned corresponding tothe second groove 36 b.

First and second protrusions 35 c and 36 c may be positioned on thefirst and second grooves 36 a and 36 b. The first and second protrusions35 c and 36 c may have a height corresponding to the first and secondsurfaces 35 a and 35 b. Namely, the first and second protrusions 35 cand 36 c may have a shape protruding from bottom surfaces of the firstand second grooves 36 a and 36 b.

As shown in FIGS. 21 and 22, the center frame bracket 70 may connect thecenter frames 30. The plurality of center frame brackets 70 may havesimilar shapes. Thus, in the following description, a description of thefirst center frame bracket 71 will be replaced with a description ofother center frame brackets 70.

As shown in FIG. 21, the first center frame bracket 71 may connect thefirst frame 31 and the second frame 32.

The first center frame bracket 71 may include a refractive portion 71 aand first and second connection portions 71 b and 71 c extended fromboth sides of the refractive portion 71 a.

The first and second connection portions 71 b and 71 c may not beparallel to each other. Namely, a second imaginary plane formed by thesecond connection portion 71 c may be inclined to a first imaginaryplane formed by the first connection portion 71 b at a predeterminedangle. Because the second connection portion 71 c is inclined to thefirst connection portion 71 b, the first and second frames 31 and 32coupled to the first and second connection portions 71 b and 71 c mayform an inclination angle AD. The inclination angle AD may serve to makethe first and second frames 31 and 32 naturally curved. The first andsecond connection portions 71 b and 71 c may be coupled to the first andsecond frames 31 and 32 by bolts coupled to the first and secondconnection portions 71 b and 71 c and through holes 31 a and 32 a of thefirst and second frames 31 and 32.

As shown in FIG. 22, the center frame bracket 70 may be configured tosimultaneously couple the frame 30 to the panel assemblies 10 and 20.For example, a related configuration may be coupled to a plurality ofdepressions formed in at least a portion of the center frame bracket 70.

The first frame 31 and the first front panel 11 may be coupled to afirst depression 71 d of the first center frame bracket 71. Namely, aninner space of the first depression 71 d may correspond to a sum of thefirst frame 31 and the first front panel 11. Similarly, the second frame32 and the third rear panel 25 may be coupled to a second depression 71e of the first center frame bracket 71. The second front panel 13 andthe fourth rear panel 27 may be coupled to third and fourth depressions71 f and 71 g of the first center frame bracket 71, respectively.

The depressions 71 d, 71 e, 71 f and 71 g may be inclined at apredetermined angle. Namely, the depressions 71 d, 71 e, 71 f and 71 gmay form an inclination angle AS and serve to make the frame 30 and thepanel assemblies 10 and 20 naturally curved.

As shown in FIGS. 23 to 25, the display device 1 according to theembodiment of the invention may include a middle frame 80.

As shown in FIG. 23, the middle frame 80 may be coupled to the sideand/or the top of the frame 30. The middle frame 80 coupled to the frame30 may serve to protect the sides of the panel assemblies 10 and 20 thatwill be coupled to the frame 30. The middle frame 80 may include firstand second side middle frames 81 and 82 coupled to the long side of theframe 30 and first to fourth top middle frames 83, 85, 87, and 89coupled to the short side of the frame 30. For example, the first sidemiddle frame 81 may be coupled to a long side of the first frame 31, andthe second side middle frame 82 may be coupled to a long side of thefourth frame 34. The first to fourth top middle frames 83, 85, 87, and89 may be coupled to short sides of the first to fourth frames 31, 32,33, and 34.

As shown in FIG. 24A, the middle frame 80 may include a body 80 d havinga first coupling hole 80 a and first and second extension portions 80 band 80 c that are extended from the body 80 d by a second distance H2 indifferent directions. The second distance H2 may be greater than a firstdistance H1 corresponding to a thickness of the frame 30.

The frame 30 may include a coupling groove 30 d. For example, a portionof the side of the frame 30 may include a stepped portion. For example,a recess having a length corresponding to the body 80 d of the middleframe 80 may be formed at the side of the frame 30.

As shown in FIG. 24B, the middle frame 80 may be coupled to the frame30. A first coupling hole 80 a of the middle frame 80 may correspond toa second coupling hole 30 c of the frame 30. A fastening member such asa bolt may be coupled to the first and second coupling holes 80 a and 30c and may couple the middle frame 80 to the frame 30.

As shown in FIG. 24C, the second distance H2 of the first and secondextension portions 80 b and 80 c may be equal to or greater than a thirddistance H3 including the panel assemblies 10 and 20 coupled to theframe 30. The panel assemblies 10 and 20 can be protected by the firstand second extension portions 80 b and 80 c extended by the seconddistance H2. For example, an impact applied to edges of the panelassemblies 10 and 20 can be absorbed in the first and second extensionportions 80 b and 80 c.

As shown in FIG. 25A, the middle frame 80 may be coupled to the frame 30in a state where first and second separation spaces SS1 and SS2 areformed. In other words, the middle frame 80 may be in a form that is notcompletely in contact with the frame 30. The middle frame 80 may benaturally inclined to the frame 30 by the first and second separationspaces SS1 and SS2. For example, an inclination angle AD between theframe 30 and the middle frame 80 may be formed.

As shown in FIG. 25B, even when the panel assemblies 10 and 20 arecoupled to the frame 30, the first and second separation spaces SS1 andSS2 may be maintained. The panel assemblies 10 and 20 may maintain theirinherent curvature R due to the first and second separation spaces 30 dand 80 d and may be coupled to the frame 30. The first and secondseparation spaces 30 d and 80 d can prevent a load that may be generatedwhen the panel assemblies 10 and 20 are coupled to the frame 30 in astate where the inherent curvature R is not maintained.

FIGS. 26 to 42 illustrate configuration of a panel assembly according tothe embodiment of the invention.

As shown in FIGS. 26 to 42, the panel assemblies 10 and 20 according tothe embodiment of the invention may be coupled to the frame 30. Thepanel assemblies 10 and 20 coupled to the frame 30 may be configured sothat a bezel area is minimized. The panel assemblies 10 and 20 coupledto the frame 30 may be configured so that the separation resulting froma concave shape or a convex shape is prevented.

As shown in FIG. 26, the first to fourth front panels 11, 13, 15, and 17and the first to fourth rear panels 21, 23, 25, and 27 may be coupled tothe front surface and the back surface of the frame 30.

The first and second front panels 11 and 13 and the first and secondrear panels 21 and 23 may have a concave shape, and the third and fourthfront panels 15 and 17 and the third and fourth rear panels 25 and 27may have a convex shape.

The first to fourth front panels 11, 13, 15, and 17 may be coupled tothe frame 30 in the order named. Namely, after the first front panel 11is coupled to the frame 30, the second front panel 13 may be coupled tothe frame 30. Further, the first to fourth rear panels 21, 23, 25, and27 may be coupled to the frame 30 in the order named in the same manneras the first to fourth front panels 11, 13, 15, and 17.

As shown in FIG. 27, each of the front panel 10 and the rear panel 20may be configured such that one panel overlaps another panel to form anoverlap area OA. For example, an overlap area OA may be formed betweenthe first front panel 11 and the second front panel 13. As describedabove, the front panel 10 and the rear panel 20 may be coupled to theframe 30 in a predetermined order. Thus, the front panel 10 may beconfigured such that the first front panel 11 is positioned under thesecond front panel 13, the second front panel 13 is positioned under thethird front panel 15, and the third front panel 15 is positioned underthe fourth front panel 17. In other words, at least a portion of an Nthfront or rear panel may be positioned on a front surface of at least aportion of an (N−1)th front or rear panel, where N is a positive integerequal to or greater than 2.

As shown in FIGS. 28 and 29, the first front panel 11 and the secondfront panel 13 may form an overlap area OA. The first front panel 11 andthe second front panel 13 may have a black matrix area.

The black matrix area may be a non-display area at the outside of adisplay panel. The display panel may include a display area and anon-display area. The display area may be an area displaying an image,and the non-display area may be an area in which an image is notdisplayed. The display area may be an active area, and the non-displayarea may be an inactive area. The non-display area may be an areanecessary for connection of display electrodes and/or touch electrodes.The non-display area may be formed along long sides and/or short sidesof the display panel. Sizes of the non-display area along a specificlong side and/or a specific short side may be different from each other.For example, a size of the non-display area corresponding to a specificside, on which a source PCB for driving the display panel is disposed,may be greater than a size of the non-display area corresponding toanother side.

As shown in FIG. 28, at least a portion of a second long side LS1 b ofthe first front panel 11 may overlap at least a portion of a first longside LS2 a of the second front panel 13. The second long side LS1 b ofthe first front panel 11 may have a 1 a non-display area BM1 a, and thefirst long side LS2 a of the second front panel 13 may have a 2 bnon-display area BM2 b.

As shown in FIG. 29, in the first front panel 11, a size of the 1 anon-display area BM1 a may be greater than sizes of 2 a to 4 anon-display areas BM1 b, BM1 c, and BM1 d. The 1 a non-display area BM1a of the first front panel 11 may overlap the 2 b non-display area BM2 bof the second front panel 13. Thus, a size of the non-display areadisplayed outside when the 1 a non-display area BM1 a overlaps the 2 bnon-display area BM2 b may be smaller than a size of the non-displayarea displayed outside when the 1 a non-display area BM1 a and the 2 bnon-display area BM2 b are disposed in parallel with each other.

The 2 b non-display area BM2 b may overlap an inner boundary of the 1 anon-display area BM1 a. Namely, the first and second front panels 11 and13 may overlap each other such that the 2 b non-display area BM2 b isthe same as or adjacent to a boundary between the 1 a non-display areaBM1 a and the display area of the first front panel 11.

As shown in FIG. 30, when the first and second front panels 11 and 13are overlapped and coupled with each other, only the non-display area ofthe second front panel 13 may be observed from the outside. For example,the 1 a non-display area BM1 a of the first front panel 11 may becovered by the second front panel 13, and the 2 b non-display area BM2 bof the second front panel 13 may be exposed to the outside. In otherwords, a non-display area WBZ observed from the outside may be smallerthan an overlap area OA when the panels actually overlap each other.

As shown in FIG. 31, the panel assemblies 10 and 20 may be positioned onthe front surface and the back surface of the frame 30. The adjacentpanel assemblies 10 and 20 may partially overlap each other.

The panel assemblies 10 and 20 may be coupled to each other by adhesivelayers 19 and 29. The adhesive layers 19 and 29 may be an adhesive or anadhesive tape corresponding to the overlap area OA. However, theabove-described coupling form of the panel assemblies 10 and 20 may beimplemented even using the center frame bracket 70 (see FIG. 22) havinga depression.

As shown in FIG. 32, at least a portion of the frame 30 may overlap thepanel assembly 10. In other words, the sizes of the frame 30 and thepanel assembly 10 may not be the same. For example, at least one of awidth and/or a length of the frame 30 may be different form at least oneof a width and/or a length of the panel assembly 10.

The panel assembly 10 may include a plurality of long sides. A firstlong side of the plurality of long sides may be at a locationcorresponding to a first long side of the frame 30. Namely, the firstlong side of the panel assembly 10 and the first long side of the frame30 may form an overlap area OA.

A second long side opposite the first long side of the panel assembly 10may not correspond to a second long side of the frame 30. Namely, thesecond long side of the panel assembly 10 may more protrude than thesecond long side of the frame 30. In other words, a non-overlap area UOAmay be formed on the second long side of the panel assembly 10.

The non-overlap area UOA may overlap not the first frame 31 but theframe 30. For example, the non-overlap area UOA may overlap the secondframe 32 next to the first frame 31. However, it is expressed as thenon-overlap area UOA in that the non-overlap area UOA does not overlapthe first front panel 11.

The formation of the non-overlap area UOA may indicate that the width ofthe panel assembly 10 is greater than the width of the frame 30. Thus,the panel assembly 10 may more protrude than the frame 30 by a widthdifference (or by the non-overlap area UOA).

The frame 30 may have a size different from the panel assembly 10.Namely, as described above, the width of the frame 30 may be differentfrom the width of the panel assembly 10. Further, the length of theframe 30 may be different from the length of the panel assembly 10. Forexample, the length of the frame 30 may be greater than the length ofthe panel assembly 10. Thus, a first short side of the panel assembly 10may be at a location corresponding to a first short side of the frame30, but a second short side opposite the first short side of the panelassembly 10 may not correspond to a second short side of the frame 30.Hence, the frame 30 may be divided into an overlap area CA and anon-overlap area UA. The non-overlap area UA may be an area where theframe 30 is coupled to the stand assembly 40.

As shown in FIG. 33, a cable CB may be positioned on the back surface ofthe panel assembly 10. Namely, the cable CB may be used to supplysignals and/or electric power required to drive a source PCB P, achip-on film (COF) C, etc. necessary for an operation of the panelassembly 10. The cable CB may be a plurality of cables including firstand second cables CB1 and CB2.

The panel assembly 10 may have long sides disposed in the longitudinaldirection. Namely, the panel assembly 10 may be disposed in thelongitudinal direction. In other words, the long sides of the panelassembly 10 may be disposed in a direction perpendicular to aninstallation surface (i.e., the ground). The source PCB P, the COF C, orthe like may be disposed on one of the long sides of the panel assembly10, and the cable CB may be extended from the one long side of the panelassembly 10.

The cable CB may be folded at least once. Namely, because the long sideof the panel assembly 10 connected to the cable CB is longitudinallydisposed, the cable CB extended in a direction parallel to theinstallation surface may be folded at least once and extended toward theground. In other words, the extending direction of the cable CB may bechanged to a direction toward the stand assembly 40.

The frame 30 may have a first groove 36 a corresponding to the cable CB.Because the relatively protruding cable CB is accommodated in the firstgroove 36 a, the panel assembly 10 and the frame 30 may be in closecontact with each other.

As shown in FIG. 34A, an insulating layer IT may be disposed on thefirst and second cables CB1 and CB2. The insulating layer IT maycorrespond to an area where the first and second cables CB1 and CB2 arebent. The insulating layer IT may be formed in a triangular and/orrectangular shape. The insulating layer IT may include first to thirdinsulating layers IT1 to IT3. The first to third insulating layers IT1to IT3 may be spaced apart from one another.

The insulating layer IT may include an adhesive layer. For example, anadhesive tape or an adhesive may be applied to one surface and/or theother surface of the insulating layer IT. The bending areas of the firstand second cables CB1 and CB2 may be attached to each other by theadhesive layer.

As shown in FIG. 34B, each of the first and second cables CB1 and CB2may be bent once. The bent first and second cables CB1 and CB2 may beadjacent to each other at the first to third insulating layers IT1 toIT3. The first to third insulating layers IT1 to IT3 can prevent theelectrical connection of the first and second cables CB1 and CB2 in thebending areas of the first and second cables CB1 and CB2. The first tothird insulating layers IT1 to IT3 may be attached to and in closecontact with one another in the bending areas.

FIGS. 35 to 42 illustrate configuration related to the coupling of thepanel assemblies 10 and 20. As shown in FIGS. 35 to 42, the displaydevice 1 according to the embodiment of the invention may include aconfiguration capable of solving the problem of coupling resulting fromthe concave and/or convex panel assemblies 10 and 20.

As shown in FIG. 35, the first and second front panels 11 and 13 and thefirst and second rear panels 21 and 23 may be formed in a concave shape,and the third and fourth front panels 15 and 17 and the third and fourthrear panels 25 and 27 may be formed in a convex shape.

Concave portions of the panel assemblies 10 and 20 may maintain theconcave shape by being supported by the frame 30 formed of a metalmaterial including aluminum, etc. For example, even when an elasticforce for flattening is generated, the concave portions of the panelassemblies 10 and 20 may be supported by the frame 30 to maintain theconcave shape.

Convex portions of the panel assemblies 10 and 20 may be spaced apartfrom the frame 30 by an elastic force for flattening. In Particular, thelast long sides of the fourth front panel 17 and the fourth rear panel27 may be separated in a separation direction DD. The display device 1according to the embodiment of the invention may include a configurationfor preventing the panel assembly 10 and 20 from being spaced apart fromthe frame 30.

As shown in FIG. 36, a deco 90 may be coupled to the panel assemblies 10and 20. The deco 90 may be coupled after a process for assembling thepanel assemblies 10 and 20. The deco 90 may include first and secondside decos 91 and 92 coupled to both long sides of the panel assemblies10 and 20 and first and second top decos 93 and 95 coupled to both shortsides of the panel assemblies 10 and 20. The decor 90 may serve as abezel.

The deco 90 may provide a beautiful appearance of the display device 1.Namely, the deco 90 may be exposed to the outside from the side of thedisplay device 1.

The deco 90 can prevent the panel assemblies 10 and 20 from beingseparated from the frame 30. Namely, the deco 90 may have a structurecapable of preventing the panel assemblies 10 and 20 from beingseparated from the frame 30.

As shown in FIG. 37A, one surface of the deco 90 may be opened. Forexample, first and second extension portions 94 and 96 may protrude toform a coupling area 51.

As shown in FIG. 37B, when the first and second extension portions 94and 96 are coupled, the deco 90 may be in the form of surrounding theside of the display device 1. In other words, at least one of the firstand second extension portions 94 and 96 may form an overlap area BOtogether with at least a portion of the display surface of each of thefront and rear panels 10 and 20. The first and second extension portions94 and 96 protruding toward the display surface may serve as the bezel.The decor 90 can protect the front and rear panels 10 and 20 and canprovide the beautiful appearance of the display device 1. The displaysurface may indicate a surface of the panel on which an image isdisplayed. Namely, the display surface may be a surface opposite theback surface of the panel.

The deco 90 may prevent the front and rear panels 10 and 20 from beingseparated from the frame 30 by the first and second extension portions94 and 96.

As shown in FIGS. 38 and 39, the display device 1 according to theembodiment of the invention may include a stand side assembly 48. Thestand side assembly 48 may serve as an interface for the componentscoupled to the stand assembly 40.

As shown in FIG. 38, the stand side assembly 48 may be coupled to thestand assembly 40. The stand side assembly 48 may be coupled to the sideassembly 40 through a fastening member such as a screw.

The stand side assembly 48 may include a first stand side assembly 48 acoupled to one side of the stand assembly 40 and a second stand sideassembly 48 b coupled to the other side of the stand assembly 40.

As shown in FIG. 39, lines LI supplying signals and/or electric powernecessary for the operation of the display device 1 may be connected tothe stand side assembly 48. The lines LI may be connected to thecomponent, for example, the T-con unit 53 a. The lines LI may beconnected to at least one of the first and second stand side assemblies48 a and 48 b.

As shown in FIGS. 40 to 42, the display device 1 according to theembodiment of the invention may include a fixture 130 for preventing theseparation of the panel assemblies 10 and 20. The fixture 130 mayinclude an adhesive and/or a magnet.

As shown in FIG. 40A, a first fixture 131 may be positioned on the frame30. For example, the first fixture 131 may be disposed along the insideof the long side of the fourth frame 34. The first fixture 131 may be amagnet. The first fixture 131 may be the second side deco 92.

As shown in FIG. 40B, a second fixture 133 may be positioned on thedisplay panels 10 and 20. For example, the second fixture 133 may bedisposed along the inside of the long side of the fourth front panel 17.The second fixture 133 may have a location and/or a shape correspondingto the first fixture 131. The second fixture 133 may be a magnet and/ora metal capable of forming an attractive force with respect to the firstfixture 131.

The second fixture 133 may be disposed at a location that does notinterfere with other components on the inner surface of the fourth frontpanel 17. For example, the source PCB P, the COF C, or the like may bedisposed on the inner surface of the fourth front panel 17. The secondfixture 133 may be disposed not to overlap the source PCB P, the COF C,or the like. For example, the second fixture 133 may be disposed in ablank area BC between the COFs C.

As shown in FIG. 41A, the middle frame 80 may have a coupling groove 80e. The coupling groove 80 e may be a recess formed in a portion of themiddle frame 80. The first fixture 131 may be inserted into the couplinggroove 80 e.

As shown in FIG. 41B, the second fixture 133 may be positioned on theinner surface of the front panel 10. For example, the second fixture 133may be positioned on the inner surface of the fourth front panel 17. Inother words, the second fixture 133 may be positioned on the fourthfront panel 17 of the convex shape.

As shown in FIG. 41C, a depth of the coupling groove 80 e may correspondto heights of the first and second fixtures 131 and 133. Thus, a sum(i.e., a fourth height H4) of thicknesses of the panel assemblies 10 and20 and the frame 30 may not increase or may be minimized irrespective ofthe formation of the first and second fixtures 131 and 133. The fourthfront panel 17 of the convex shape may be stably attached to the frame30 due to magnets, that have an attractive force between them, and/ormetal bodies (i.e., the first and second fixtures 131 and 133)corresponding to the magnets. Further, although not shown, the deco 90(see FIG. 37) may be coupled, in addition to the first and secondfixtures 131 and 133.

As shown in FIG. 42A, a separation area 34 b may be provided between theinner surface of the fourth front panel 17 and a coupling surface 80 fof the middle frame 80. The second fixture 133 may be positioned in atleast a portion of the separation area 34 b. The fourth front panel 17may naturally bend depending on its inherent curvature due to theseparation area 34 b.

As shown in FIG. 42B, the first fixture 131 may be formed on the frame30. For example, the first fixture 131 may be disposed on one side ofthe fourth frame 34. The second fixture 133 may be disposed on the innersurface of the fourth front panel 17 corresponding to the first fixture131. The second fixture 133 may be a magnet and/or a metal body. Such astructure may be applied to a case in which a sufficient space is notsecured in the middle frame 80 and/or the inner area of the front panel10 corresponding to the middle frame 80.

FIGS. 43 to 48 illustrate configuration of a cover assembly according tothe embodiment of the invention.

As shown in FIGS. 43 and 44, a stand supporter 107 may be coupled.

Bottom fixers 105 may be positioned at locations corresponding to eachother on both side surfaces of the frame 30. For example, a first bottomfixer 105 a may be positioned on one side surface of the frame 30corresponding to the front panel 10, and a second bottom fixer 105 b maybe coupled to the other side surface of the frame 30 corresponding tothe rear panel 20.

The stand supporter 107 may support a stand cover 110 (see FIG. 45).Namely, the stand supporter 107 may be a component to be coupled to anupper side of the stand cover 110.

The stand supporter 107 and the bottom fixer 105 may be coupled to theframe 30 by fastening means 102 and 104. The fastening means 102 and 104may include a bolt 102 and a nut 104.

As shown in FIGS. 45 to 48, the display device 1 according to theembodiment of the invention may include the stand cover 110, stand sidecovers 112 and 114, and a bottom deco 100.

As shown in FIG. 45, the stand cover 110 may have a structure forshielding the stand assembly 40. Namely, the stand cover 110 may have astructure for forming an appearance of the stand assembly 40 in whichvarious components are installed.

The bottom deco 100 may be positioned under the panel assemblies 10 and20.

Namely, a back surface 108of the 1 a bottom deco 101 a may include a stepped portion having theheight difference of the first distance HD1. A thickness of the 1 abottom deco 101 a in the first area A1 may be expressed as T1, and athickness of the 1 a bottom deco 101 a in the second area A2 may beexpressed as T2. The first distance HD1 may be formed corresponding to athickness of the second front panel 13.

A boundary between third and fourth areas A3 and A4 of the 1 b bottomdeco 101 b may have a height difference of a second distance HD2. Thesecond distance HD2 may correspond to a thickness of the fourth panel17.

The thickness of the bottom deco 100 may vary from the first thicknessT1 to a fourth thickness T4. Namely, the thickness of the bottom deco100 may decrease in order to offset the thicknesses of the panelspositioned on the back surface 108. The 2 a and 2 b bottom decos 103 aand 103 b may be in a shape symmetrical to the 1 a and 1 b bottom decos101 a and 101 b.
